Oral manifestations in paediatric patients with hepatobiliary diseases: a review.

J Biol Regul Homeost Agents 2021 May-Jun;35(3 Suppl. 1):117-125

Department of Surgical, Medical, Molecular and Critical Area Pathology, Unit of Pediatric Dentistry, University of Pisa, Pisa, Italy.

It is well known that greenish pigmentation of the teeth is seen in children following remission of severe jaundice and clinical and serum bilirubin, a degradation product of haemoglobin, may be permanently trapped in forming dental hard tissues causing discolouration and enamel and dentine hypoplasia. Neonatal jaundice is the most common cause of hyperbilirubinemia and pigmentation of the deciduous teeth is the consequence of this condition. Various hepatobiliary pathologies may have a clinical finding in the oral cavity; furthermore, oral manifestations of hepatic pathologies are not just limited to the pigmentation of the deciduous teeth but also the permanent dentition and the mucous membranes can be affected.
